As part of their ongoing challenge of the signatures gathered for Green Senate candidate Carl Romanelli, the Pennsylvania Democrats are analyzing them for fraud. And William J. Ries, a forensic document examiner working for them, has found that a petition signed by John Michael Glick, a Santorum staffer (of duck costume fame), has four "questionable" signatures. http://www.tpmmuckraker.com/archives/001277.php

The signatures belong to family members of another fellow staffer, Julianne George, Santorum’s Deputy Director of Coalitions. You can see a side by side comparison of the signatures: http://www.talkingpointsmemo.com/docs/green-signatures/

“The writing expert’s findings raise serious questions, not only about the illegal financing of the petition drive paid for by Santorum backers but how he authorizes the use of campaign staff for apparent fraud," Pennsylvania Democratic Party Chairman T.J. Rooney said.

Democrats say that more than 69,000 of the approximately 100,000 signatures gathered by Santorum staffers and JSM, Inc., a private company hired by the Greens with Republican money, are fraudulent.
